  Title: Sunset
  Description:
  This cross section of the Earth's atmosphere at sunset and earth limb
  (24.5S,  43.5E) displays an unusual layering believed to be caused by
  temperature  inversions which effectively concentrate smoke, dust and
  aerosols into narrow  layers.  the top of the stratosphere can be seen as
  the top of the white  layer thought to contain volcanic debris.  The purple
  layer is the  troposphere containing smoke from landclearing biomass
  burning.
